Sunrise, sunset and daylight hours explained
What time is sunrise today? It depends on three things: where you are on Earth (latitude and longitude), the date, and your time zone. The sunrise and sunset times on this page are calculated for each city's coordinates using the solar position equations published by NOAA, and shown in local clock time — so daylight saving time is always included.
Why day length changes through the year
The Earth's axis is tilted about 23.4°. As the planet orbits the Sun, each hemisphere leans towards the Sun for half the year, giving long summer days, and away for the other half, giving short winter days. The change is fastest around the spring and autumn equinoxes (around 20 March and 22 September), when places like London or New York gain or lose two to four minutes of daylight every day. Around the summer and winter solstices the day length barely changes from one day to the next.
Latitude makes the biggest difference
Near the equator — Singapore, Nairobi, Bogotá — there are about 12 hours of daylight all year. Further from the equator the seasons get extreme: Oslo has close to 19 hours of daylight at midsummer and under 6 hours in December, while Reykjavik sees barely 4 hours of sun at the winter solstice. North of the Arctic Circle the Sun does not set at all in summer (the midnight sun) and does not rise in winter (polar night). The southern hemisphere has the opposite pattern: Sydney, Melbourne and Buenos Aires have their longest days in December.
Twilight, golden hour and solar noon
The sky is light before sunrise and after sunset. Civil twilight — when the Sun is less than 6° below the horizon — is shown as dawn and dusk above. Photographers often plan around the golden hour, roughly the first and last hour of sunlight, when light is soft and warm. Solar noon is when the Sun is highest; it can be well after 12:00 in places with daylight saving time or wide time zones, such as Spain or western China.
Planning with sunrise and sunset times
Use the 14-day table to plan runs, hikes, photography, fishing trips or prayer times, and the major cities list to compare daylight around the world. For the current time in each city, see the world clock; to see when clocks change, check the time zones page and the 2026 and 2027 calendars with week numbers.
